Abstract
A power amplifier is disclosed for amplifying an input signal and providing an amplified signal to a load at a junction node. The power amplifier comprises a splitter network, a carrier amplifier path and a peaking amplifier path. The peaking amplifier path comprises a first impedance transformer coupled between a peaking output matching network and the junction node to enhance the off-state impedance of the peaking amplifier. The carrier amplifier path comprises a second impedance transformer coupled between a carrier output matching network and the junction node.
